Abstract
A cylinder liner in a power assembly for an engine includes an elongate liner body including a water jacket surface and a plurality of combustion air ports extending from an outer liner surface to an inner liner surface. A coolant supply passage extends from a coolant inlet formed in an outer liner surface, to a water jacket feed outlet spaced axially from the plurality of combustion air ports. A flow balancer for coolant is positioned in a coolant flow path extending in an axial direction along the water jacket surface from the water jacket feed outlet. The cylinder liner may form, in service in an engine, an upper water jacket, and a lower air annulus. The flow balancer assists in normalizing a flow and pressure of coolant through the water jacket.
